A conductive terminal for a flat flexible cable comprises a first contact surface, and a second contact surface opposing the first contact surface. The first and second contact surfaces define a space therebetween for receiving a flat flexible cable along a longitudinal direction of the terminal. A dimpled structure is defined on the first contact surface and includes a plurality of dimples extending from the first contact surface in a direction of the second contact surface. The dimpled structure includes at least one dimple having a first height, and at least one dimple having a second height, distinct from the first height.

A battery pack includes: a plurality of battery cells; a battery management system to acquire state information and control charge-discharge operations; a wiring board through which the state information is transmitted to the battery management system, the wiring board including conductive lines for transmitting different electrical signals; and a connector including a connector terminal coupled to the conductive lines and a connector housing accommodating the connector terminal, the connector being coupled to a mating connector of the battery management system, wherein the connector terminal includes a bottom plate accommodating the conductive lines, and barrels protruding upward from the bottom plate and configured to be compressed onto the conductive lines while surrounding the conductive lines, and first and second embossments on the bottom plate and the barrels of the connector terminal, the first and second embossments protruding toward the conductive lines.

A crimp terminal-equipped flexible printed circuit board includes: a first flexible printed circuit board having a base film and a circuit provided on a surface of the base film and made of metal foil; multiple crimp terminals including crimp pieces crimped to penetrate the first flexible printed circuit board and bent to bite into part of the circuit; and an insulating reinforcing film partially integrally provided on an area of the base film where the multiple crimp pieces penetrate.

A cable assembly includes a flat flexible cable having a plurality of conductors embedded within an insulation material. A portion of each of the conductors is exposed via openings selectively formed in the insulation material, allowing for a crimping portion of an electrically conductive terminal to engage with the conductor within the opening. The crimping portion of the terminal includes a base defining at least one protrusion extending therefrom, and first and second sidewalls extending from the base. The base and the first and second sidewalls define an opening configured to receive the conductor therein. The first sidewall includes a first section attached to the base and a second section attached to the first section on an end opposite the base. In a crimped state of the terminal, the first sidewall rotated into the opening such that the first section at least partially surrounds the second section, and the second sidewall is rotated in a direction opposite the first section such that the first section at least partially surrounds the second section, for crimping the conductor within the opening and against the protrusion.
